Trident Hose

<p>Founded in 1985, Trident Marine has focused on producing hoses that excel in durability, performance, and reliability, earning recognition as the oldest North American marine hose company. With decades of experience engineering specialized solutions for the demanding marine environment, Trident has become a trusted name among boaters, yacht owners, and marine professionals who require components that can withstand saltwater corrosion, extreme temperatures, engine vibration, and constant exposure to the elements.</p> <h3>Marine Hose Engineering Excellence</h3> <p>Trident Marine's product portfolio addresses virtually every fluid transfer and exhaust need aboard modern vessels. Trident Marine brings aboard marine hose, tubing, ducting, conduit and flexible wet exhaust connectors to the marine market worldwide. Each product line is engineered with materials specifically selected for marine applications—from FDA-compliant compounds for potable water systems to high-temperature silicone formulations that withstand the punishing conditions of <a href="./m/7617/c/201177">wet exhaust systems</a>.</p> <p>Trident Marine's wet exhaust hoses are designed for marine wet exhaust systems, offering much greater tolerance to heat, misalignment, engine movement, and vibration. The company's corrugated designs allow for complex routing with substantial bends, while premium silicone options deliver exceptional temperature resistance and service life. For vessel owners dealing with onboard sanitation, Trident's <a href="./m/7617/c/200897">sanitation hose</a> products are designed for head and holding tank connections on boats and engineered to resist odor permeation—a critical feature in enclosed marine environments.</p> <h3>LPG Systems and Safety Components</h3> <p>Beyond hose products, Trident Marine also builds and supplies Marine LP Gas Systems. The company's comprehensive <a href="./m/7617/c/200642">LPG product accessories</a> include everything from high-pressure thermoplastic hoses and regulators to complete propane lockers that safely contain cylinders, regulators, and solenoids. Trident Marine's LPG hoses are high-pressure, thermoplastic, flexible, and fully assembled with leak testing, ensuring systems meet ABYC marine standards for safe galley operation.</p> <h3>Fuel System Integrity</h3> <p>Trident's <a href="./m/7617/c/200442">fuel hose</a> offerings represent another area where the company's engineering focus delivers real-world benefits. Their Trident fuel hose is engineered to meet strict industry standards, providing superior resistance to harsh marine conditions, fuel degradation, and temperature extremes. With barrier-lined construction compatible with both gasoline (including ethanol blends) and diesel fuels, these hoses protect against permeation while maintaining flexibility in tight engine compartments.</p> <h3>Specialized Marine Applications</h3> <p>For below-waterline applications, Trident manufactures dedicated <a href="./m/7617/c/200165">bilge and livewell hose</a> products designed to handle continuous water exposure. The company also produces heater hoses, air conditioning ducting, electrical conduits, and wash-down hoses—each formulated for specific temperature ranges, pressure ratings, and chemical resistance requirements. Each product is built with high-grade materials and designed to maintain system integrity, reflecting Trident's understanding that component failure at sea isn't just inconvenient—it can be dangerous.</p> <p>Whether you're maintaining a weekend fishing boat, outfitting a commercial vessel, or building a luxury yacht, Trident Marine's specialized hose and LPG system components deliver the reliability that marine applications demand.</p>
